Counting earthlings is not done out of simple curiosity. For a normal life, each of us needs a certain amount of water, air, food. In turn, each of the inhabitants of the Earth affects the environment. Therefore, it is very important to know how many people live on our planet.
What do earthlings think?
In order to find out how many people live on Earth, you need to identify their number in individual countries and regions of the planet. In most countries, the population is determined using general population censuses. They are held regularly once every 5 or 10 years. But in some countries and areas of the world, censuses were either not conducted at all, or were conducted for a very long time. Therefore, the total number is determined using special calculations.
How many people are there now?
A little less than 7.4 billion people currently live on Earth. For many millennia, the number of people on Earth was small and did not increase very quickly. But since the 19th century. the rapid population growth began, which continues to this day.
What influences the growth of the number of people?
The growth in the number of people depends on many reasons. This is the level of development of the country, and the well-being of people, and national traditions. Until now, the reasons for the change in the number of the world's inhabitants are hunger, disease and war, as well as natural disasters.
Population change is determined by the ratio and mortality. At present, 21 people are born every second in the world, and 18 people die. As a result, it grows daily by 250 thousand people. But in different periods of human history and in different regions of the Earth, the value is not the same.
The average age of the inhabitants of these countries also depends on the state of birth and death rates in different countries. Countries with high population growth have many children and young people. Low-growth countries have a high proportion of older people.
MOSCOW, July 25 - RIA Novosti. The world's population will reach 10 billion in 2053, but the number of inhabitants in Russia and Ukraine will decrease by 7.9 and 9 million, and in Japan - by a "record" 24.7 million, according to the Washington-based Population Bureau (PRB ).
"Despite the general decline in the birth rate across the planet, the rate of population growth will remain high, which will be enough to reach the 10 billion mark. Of course, the picture in different regions will be strikingly different - for example, the number of inhabitants Europe will continue to fall, while Africa's population will double by 2050, ”said Jeffrey Jordan, President and Director of the Bureau.
This non-profit organization is today one of the world's leading global demographic forecasting bureaus, publishing annual reports and estimates of global population growth since 1962. This year, according to Jordan, the quality of forecasts has been improved by adding six new demographic indicators that take into account how the availability of different resources affects population growth.
According to new PRB forecasts, the population of the planet will approach 9.9 billion by 2050, and in 2053 it will cross the 10 billion mark. Most of this growth will come from Africa - its population will grow to 2.5 billion by that time. At the same time, the number of inhabitants of America will increase by only 223 million, Asia - by 900 million, and the number of inhabitants of Europe will decrease by about 12 million.
The world's population will exceed 10 billion by 2100The world's population will surpass 10 billion by 2100, and possibly close to 15 billion if global fertility rises slightly, according to a report by the United Nations Population Fund (UNFPA), presented in London on Wednesday.The main socio-demographic problem of this growth will be that almost all of this growth will occur in the most underdeveloped states of the Earth. The PRB estimates that the population of the world's 48 most underdeveloped states will double by 2050 to nearly two billion. Moreover, in 29 states from this list, almost all of which are in Africa, the population will more than double. The population of Niger, for example, will triple by mid-century.
On the other side of the "table of ranks", the situation is the opposite - the population will decrease mainly in all developed countries, except for the United States, in a total of 42 countries of the world. The traditional "leader" in this respect will be Japan, where the number of inhabitants will be reduced by almost 25 million, and its close competitors will be Russia, Ukraine and Romania.
The world population on January 1, 2016 will be almost 7.3 billion peopleThe most populous country, according to statistics, is China, followed by India and the United States. Russia, with 142.423 million inhabitants, ranks ninth.With all this, the top three "ten" countries in terms of population will remain the same - India, China and the United States. Below there will be a series of permutations, and Nigeria will rise to fourth place, Indonesia will descend to fifth place, and Brazil - to seventh.
Such population growth in the poorest and most disadvantaged countries of the world, according to PRB experts, speaks of the urgent need for an early transition to a sustainable development economy to provide this mass of people with the necessary resources and basic necessities without causing critical damage to the planet.
Remember:
Question: What is the number of people on Earth?
Answer: the population is constantly changing, currently it is about 7.4 billion people
My geographic research:
Question: How many years did it take for people to reach 1 billion people (Figure 2.2)
Answer: by 1830, the population was about 1 billion people
Question: How did the periods of time change in the future, during which the number of inhabitants of the Earth increased by 1 billion.
Answer: The population of the Earth began to grow at a phenomenal, explosive rate.
Approximately 100 years after reaching the billionth level (1830), it reached 2 billion, 30 years later - 3 billion, etc.
There are 7.4 billion people living on Earth now. According to UN calculations, in the coming years this figure will increase by an average of 78 million annually, and by 2050 it will reach 9 billion. Population growth will continue mainly in the most populous and poor regions.
Question: What, according to the calculations of scientists, will be the number of earthlings in 2050? How much will it increase compared to the current population?
Answer: According to scientists' forecasts, by 2050. the number of earthlings will be about 9 billion. people, and in comparison with 2016 will increase by 1.6 billion people
Questions and tasks:
Question: Why are population censuses carried out?
Answer: The objectives of the population census are economic in nature. To know how much water, food, household items, clothing, transport, etc. is needed for the population today and how much will be needed tomorrow. For production planning, in order to provide the population of the country (planet) with the conditions necessary for life, you need to know how many people live in a particular country, mainland, or the world; for this, a population census is carried out, which is carried out once every 5 or 10 years. In Russia, the population census has been conducted since 1897.
Question: How did the rate of population growth change?
Answer: Until 1800. the population grew at a slow pace, no more than 10 million in a hundred years.
The world's population is currently growing at a rate of about 1.15% per year. Average annual population changes are currently estimated at more than 77 million (i.e. 1 billion + 1 year \u003d 1.07 billion, etc.).
Annual growth rates peaked in the late 1960s, when the figure was 2% or even higher. The growth rate has therefore nearly doubled since its peak of 2.19 percent, which was achieved in 1963 at the current 1.15%.
The annual growth rate is currently declining and is projected to continue to fall in the coming years, however the rate of future change is still unclear. It is currently projected to be less than 1% by 2020 and less than 0.5% in 2050.
This means that the world's population will continue to grow in the 21st century, but at a slower pace than in the recent past. The world's population has doubled (100% increase) in the 40 years from 1959 (3 billion) to 1999 (6 billion). It is currently estimated that a 50% increase will take another 42 years, in 2050 the mark will exceed 9 billion.
Question: What are the reasons affecting the population size?
Answer: The reasons influencing the population size include the level of economic development of the country, the level of education and well-being of an individual, national and religious traditions, such social phenomena as hunger, disease, as well as natural disasters, and the most terrible offspring of mankind - war.
Question: What indicators determine the change in population size?
Answer: The change in population is determined by the ratio of fertility and mortality; the positive difference between fertility and mortality is an indicator called Population growth.
Question: Name the mainland in the countries of which the natural population growth is greatest.
Answer: mainland Africa.
There are more than 200 states on planet Earth (including partially recognized and unrecognized countries).

They all differ in terms of living standards, incomes of the population, cultural development and other important indicators.
In this situation, it is natural that the number of inhabitants of the countries of the world differs significantly.
Against the background of states with a huge number of inhabitants, there are countries where literally several thousand people live.
common data
According to various estimates, 7.444-7.528 billion people live on the planet Earth. Population growth is constantly observed by about 90 million people.
But the distribution of inhabitants around the planet is extremely uneven. More than 1/3 of all humanity lives in China and India, and 2/3 of the world's inhabitants live in the 15 most populous countries.
For comparison, we present in the table information on the population of the planet in different periods of human development:
Note. Data for 1500 and earlier are derived from scientific assessment. At this time, accounting and census were not yet engaged.
Basic indicators
The population of each country is taken into account by both local authorities and the international scientific community.
In this case, data obtained as a result of censuses, keeping migration records, etc. are used. In some states, it is almost impossible to estimate the exact number of inhabitants.This is hindered by military conflicts, and part of the population of some countries lives in extremely hard-to-reach areas.
Consider how much the population of the earth is by state for 2020 in the following table:

Leading countries
Most of all people live in China and India. In total, more than 2.740 billion people live in these two states.
Ranking 3rd in terms of the number of residents, the United States lags behind any of these countries very significantly, because they are home to only 325.719 million people.
In Russia, which is in 9th place, there are even significantly fewer people - 146.880 million people.
Who's lagging behind
On the political map of the planet, there are also states with a very small number of inhabitants. Least of all people live in the Vatican (less than 850 people).
But this does not mean that a sparsely populated country is an exception to the rule. There are also full-fledged states with literally several thousand inhabitants.
For example, only about 10 thousand people live in Tuvalu or Nauru. Less than 50 thousand people live in states such as Palau, San Marino, Liechtenstein, Monaco.
Growth dynamics
For a long time, the number of people on planet Earth was relatively small. It began to grow significantly only in the 19th century, but the real population explosion occurred in the 1960s and 1980s.
It is associated with an increase in the availability of quality medical care, a general increase in living standards and a continuing birth rate in a number of countries.
Most of the newborns are in countries such as China and India. Many in the states of Latin America, as well as Africa.
Forecast for the future
Scientists are constantly considering various scenarios for the further development of mankind and changes in the number of inhabitants of the planet.
According to them, by 2020 there will be about 7.7-7.8 billion people living in the world and in the future it will only increase.
According to forecasts, by 2030 there will be more than 8.463 billion people on the planet, and by 2050 - already 9.568 billion.In 2100, the Earth's population may reach 11 billion.
The number of inhabitants on our planet is growing every day. This is due to many factors and does not happen in the same way. Therefore, it is very difficult to keep track of how many people live in the world. However, approximate data still exist.
Population of the planet
Today, there are about 7 billion people in the world, it is difficult to name exact data, since someone is constantly born and someone dies. For the most part, the number of the population of a country depends on several factors, including the level of development of the state and, in particular, medicine, the standard of living and even the temperament of a person.
Many centuries ago there were much fewer people on Earth, but over time this figure grew rapidly. Despite world epidemics, diseases and terrible ones continue to multiply and populate every part of the planet. Most of the population lives in the most developed megacities, where the standard of living is higher than in small cities, the same applies to countries. About half of the people live in the most populous countries.
China
The first place rightfully takes this country almost reaches the figure of 1.5 billion, that is, almost 1/5 of the number of people in the world today. Despite the fact that the state authorities are trying in every possible way to deal with the regulation of the birth rate, the number of inhabitants of the country is still growing rapidly, increasing by about 8.7 million annually.
India
If we talk about how many people are in the world now, then the second place among the most populated states belongs to India. It is home to about 1.17 billion people, which is about 17% of the total world population. The annual population growth in this country is about 18 million people, that is, the Indians have every chance of being overtaken by the number of Chinese.
USA
With a steady influx of immigrants from less developed neighboring countries, the United States is among the most populous countries in the world. This state is home to about 307 million people of various nationalities.
Indonesia
The fourth position in the list is occupied by a state located in Southeast Asia. About 240 million people live on its territory, which is about 3.5% of the total
Brazil
The first five is concluded by this sunny country, which is also the most populated state in South America. Exactly 3% of how many people in the world live in Brazil. The number of inhabitants of this state reaches 198 million inhabitants.
Pakistan
The sixth place belongs to Pakistan, which, according to the latest data, has about 176 million inhabitants, which make up 2.6% of the total population of our planet.
Bangladesh
The country, located in South Asia, is home to 156 million people. That is, the number of Bangladeshis is about 2.3% of the inhabitants of the planet Earth.
Nigeria
This African country is also in the top ten in terms of population. The number of people living here reaches 149 million, that is, 2.2% of all people on the planet. In addition, Nigeria also holds a leading position in terms of fertility, which may soon help it overtake Bangladesh.
Russia
A significant part of how many people live on the planet is in Russia. Despite the fact that Russia is only in 9th place in terms of population. This is due to the fact that mortality here significantly exceeds the birth rate. The territory of this state accounts for about 2% of the population of the entire Earth, that is, about 140 million people.
Japan
The top ten is closed by the Land of the Rising Sun, which, however, is the most developed of all those presented above. It is home to approximately 127 million people, that is, 1.9% of the earth's population. What is important, since the country is in a somewhat conserved state, almost all of its population is native Japanese.
Output
The World Health Organization regulates the population of states and controls how many people in the world. In order to somehow reduce the birth rate in very poor African countries, missionaries are regularly sent there who give lectures to the local population and provide them with the necessary contraception. Other states are taking other measures. For example, in China, the authorities are struggling with too high fertility rates by imposing taxes on families who want to have more than one child. But such measures are extremely necessary, because the resources of our planet are limited, and they are greatly influenced by how many people in the world. Therefore, it is simply necessary to avoid in order to prevent an environmental catastrophe and serious depletion of all natural resources of our planet Earth in the future.
